摘要： Methods, systems, and devices for wireless communications are described that support non-periodic channel state information (CSI) triggering and reporting in wireless communications. In cases where two or more CSI report requests trigger multiple CSI report transmissions in an same uplink slot, a user equipment (UE) may format at least a subset of the multiple CSI reports according to a formatting configuration for transmission of multiple CSI reports in a same uplink slot. The UE may use allocated resources in the uplink slot for each CSI report that are allocated by the base station in the corresponding CSI report request. In some cases, the UE may combine the multiple CSI reports, or parts thereof, into a combined CSI report that may be transmitted using allocated resources of one of the CSI report requests.

摘要： Aspects of the present disclosure provide methods and apparatus for selecting beamforming parameters for uplink transmissions based on an uplink reference signal. An example method generally includes identifying one or more parameters for beamformed transmission to a transmit receive point (TRP), transmitting a reference signal using beamforming in accordance with the identified parameters, and receiving, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions.

摘要： Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

摘要： Aspects of the present disclosure describe receiving, from an access point, an indication of at least one of a beamforming method for beamforming a RS or a normalization method for normalizing power for beamforming the RS. A channel covariance matrix corresponding to interference over a plurality of antenna ports can be generated, as well as a RS beamforming matrix based at least in part on modifying the channel covariance matrix and on the normalization method. The RS can be generated based on the RS beamforming matrix and the beamforming method. The RS can be transmitted to the access point based on the RS beamforming matrix.

摘要： Methods, systems, and devices for wireless communications are described for configuration and transmission of one or more uplink reference signals for tracking. A user equipment (UE) may transmit one or more uplink reference signals for tracking and a base station or transmission-reception point (TRP) may estimate one or more frequency or time shifts (e.g., a Doppler shift, time shift, or both) associated with communications with the UE. The estimated frequency shifts, time shifts, or combinations thereof, may be used to provide compensated communications (e.g., Doppler compensated communications) with the UE. The uplink reference signal for tracking may be a sounding reference signal that is configured as a tracking reference signal.

摘要： A method of wireless communication, by a user equipment (UE) supporting a four transmitter/six receiver (4T6R) antenna configuration, reports a sounding reference signal (SRS) switching capability. The method receives an SRS antenna switching configuration, and performs SRS antenna switching while transmitting multiple SRSs via SRS resources with multiple transmitters for different antenna ports, in accordance with the SRS antenna switching configuration. At least one of the different antenna ports may use at least two of the SRS resources. A quantity of the different antenna ports assigned to each SRS resource may be different for the SRS antenna switching. The UE may sound the different antenna ports an equal number of times, and at least one of the different antenna ports may use at least two of the SRS resources for the SRS antenna switching.
